Hunter.io

Hunter.io is an email search and outreach platform designed for sales teams, recruiters, and marketers who need to find and verify professional email addresses. The tool scans domains and public sources to identify email patterns associated with a company, returning likely contact addresses tied to names and job titles. Its email verifier checks deliverability by confirming whether an address is valid, reducing bounce rates for outreach campaigns. Hunter also offers a Campaigns feature that lets users send and track cold email sequences directly from the platform. The service integrates with tools like Google Sheets, Salesforce, and HubSpot via API and browser extensions, enabling users to build prospect lists and automate lead generation workflows.
